I have no problems installing other dependencies but djangorestframework_simplejwt gives me the following error.
Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProtocolError('Connection aborted.', ConnectionResetError(54, 'Connection reset by peer'))': /packages/3d/d7/92c717da4e3474fef8a5415391170eba60be16a4e531c9027c38b2c329c8/djangorestframework_simplejwt-3.2.3-py2.py3-none-any.whl

EDIT
It seems to be a problem with my virtualenv. When I deactivate it then pip works fine.
WORKAROUND
So I found a workaround for the time being. I deactivated my env, then did pip install djangorestframework-simplejwt, then source bin/activate to activate my env. Then I would run pip install djangorestframework-simplejwt, it would use the cached version.

I have installed CPython [1] on my local machine (macOS Catalina, v. 10.15.4) to speed up computations for function optimize_graph_edit_distance in networkx package. Before, I was running the code on Python3, which takes a lot of time. However, when I run the code with CPython (the alias for CPython is python3), I obtain the following error:
Traceback (most recent call last):
File "/Users/olha/Desktop/GED_optima.py", line 3, in <module>
import networkx as nx
ModuleNotFoundError: No module named 'networkx'
I tried python3 -m pip3 install networkx, but I got the following error:

Does anybody knows how to install networkx on CPython?
Thank you!

You can install networkx by:
git clone https://github.com/networkx/networkx.git
cd networkx
sudo python setup.py install
Try running the following command (Copied from Mayur Deshmukh's answer to ssl not available):
python3 -m pip install --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org --upgrade pip
I am kind of new with docker-compose. Terminal displays this message when building container. Not sure where the problem is.

Thanks for you help
I see that you use python2.7.
It is unsupported since january 2020. It is possible your problem comes from here.
Your build environment does not recognize the SSL certificate of https://files.pythonhosted.org as valid.
If the root certificate of files.pythonhosted.org was added in a more recent python version, that may explain it.
I strongly advise to find a way to update your python to python3 before anything else.
python pip is not working behind proxy
I tried
sudo -H pip --proxy https://proxy_ip:proxy_port install <package>
sudo -H pip --proxy https://usename:password#proxy_ip:proxy_port install <package>
sudo easy_install pip
and nothing is working, I also tried setting environment variables HTTP_PROXY but it isn't working.
For instance, here is the error when trying to install toolz:
Collecting toolz
Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', error('Tunnel connection failed: 407 Proxy Authentication Required',))': /simple/toolz/

Retrying (Retry(total=2, connect=None, read=None, redirect=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', error('Tunnel connection failed: 407 Proxy Authentication Required',))': /simple/toolz/

I use pip install behind a proxy frequently. Here's the syntax that's working for me:
sudo pip --proxy username:password#ip_address:port install <package_name>
The problem was within a conf file that loads old proxy settings. Also the environment variables are case sensitive. So check if there is a difference between HTTP_PROXY and http_proxy by using printenv in linux
Then as #MedAli suggested: adding --proxy while using pip will work
I'm triying to install Tensorflow, and I get the following:
C:\>pip3 install --upgrade tensorflow
Collecting tensorflow
Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by
ConnectTimeoutError(<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x00000240DAD78BA8>, 'Connection to pypi.python.org timed out. (connect timeout=15)')': /simple/tensorflow/
I've also tried to install it downloading the .whl on the GitHub repository, and I get the same kind of error:
C:\>pip3 install tensorflow-1.1.0-cp35-cp35m-win_amd64.whl
Processing c:\tensorflow-1.1.0-cp35-cp35m-win_amd64.whl

My PC is connected to my university's network which need a HTTP proxy configuration. Could it be the problem? How could I fix it?
So pip work abruptly behind proxy for that you can refer Using pip behind a proxy
But for your alternate you can download Tensorflow wheel from (Python 2 CPU)
